ABSTRACT:
An improved cooling system wherein printed circuit cards are made into modules of two cards each with an enclosed space between them inside the module. The modules cooperate with a rack which carries air passages, and upon connection of the module into the rack, air flows from one side of the rack through the module space, thus cooling the cards from their rear surfaces, thence out of the module, and returned via the other side of the rack.
